Across TCGA pan-cancer cohorts, SNORD113-9 RNA is linked to patient survival in 17 of 34 cancer types, making it the most broadly survival-associated SNORD113-9 data layer compared with 1 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher SNORD113-9 RNA is associated with worse overall survival. In most high-consensus cancer types, elevated SNORD113-9 expression acts as an unfavorable survival marker, although some lineages such as LAML and PAAD show a favorable association.
HNSC, KICH, and COAD are the cancer types where SNORD113-9 RNA most reproducibly stratifies survival.
RNA survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
